still unable to save

When I'm playing pokemon emerald on google chrome and I try to save it doesn't work. I press fn + f1 and all it does is just freeze the game. I unfreeze the game by pressing fn + f2. I press the save button below the game and it asks if i want to over ride previos save which I click yes to. But when I press the load button, nothing happens. I am at a lost of words on what to do. Help?
